It can be hard to stay focused(专注的）all day at school.But {#blank#}1{#/blank#} (luck),the subjects change,so you don't need to focus on the same subject all day long.Each subject {#blank#}2{#/blank#}  (last)for a limited time,{#blank#}3{#/blank#} you just need to focus for limited periods of time.There is usually a short break as you change books and other things for {#blank#}4{#/blank#}  new subject.

    At school,if your mind wanders(漫游)while you're listening or doing work at your seat, you'd better change the way you're sitting.In that way,you will become more {#blank#}5{#/blank#}  (comfort). Take a deep breath,so you can better listen to {#blank#}6{#/blank#}  is being said.

    To keep your mind on the work,talk to yourself about it.Ask yourself questions about what you need to do,then answer the questions and do the things you need to do.Do one thing at a time till you get it completely {#blank#}7{#/blank#} (do).

    If the work is hard,don't just give {#blank#}8{#/blank#} .Give it a try or ask for help.{#blank#}9{#/blank#}  (put)it off won't help you do it,and that won't make the work any easier.Give {#blank#}10{#/blank#} (you)brain a challenge--it's good exercise!

    My teachers thought I was the worst student. My family also had the {#blank#}1{#/blank#} thought as my teachers. When I was going to give up my studying, a new teacher, Miss White came to our school. She was young, {#blank#}2{#/blank#} (beauty) and knowledgeable (知识渊博的). One day, I was sitting alone in my class-room, Miss White came up to me and talked to me {#blank#}3{#/blank#} (happy). Soon her smile took away my unhappy. “Do you think I can go to college?” I didn't {#blank#}4{#/blank#} (know) why I asked such a question. I thought she must say “no”. {#blank#}5{#/blank#} (because) everyone else said so. But she said, “Dear, you can do{#blank#}6{#/blank#} (something) you want. Just try, and you'll get closer to success. I believe you are the best!” I was touched deeply{#blank#}7{#/blank#}her words. I decided to study hard. From then on, we became good {#blank#}8{#/blank#}(friend). She often helped me my study in her free time. In the end, I {#blank#}9{#/blank#} (do) well in my studies and went to a good college. Miss White is an angel(天使). Her words have kept me going forward. She helped me to see that I am special and can be {#blank#}10{#/blank#} (succeed) in life.

    "After walking through the mirror, many strange things happened to Alice. One day, she{#blank#}1{#/blank#} (meet) a unicorn(独角兽).'What－is－this? 'the unicorn asked its friend. 'That is a child,' {#blank#}2{#/blank#} (reply)the friend. 'Ah,' said the unicorn, I always thought they were fabulous monsters(传说中的怪兽)! Is it alive？'Alice then said, "Do you know,' I always thought unicorns, were fabulous monsters {#blank#}3{#/blank#}? I never saw one alive before!'"

    Fifty years before Lewis Carroll (1832-1898) wrote{#blank#}4{#/blank#} (he) stories about Alice, many people still believed in the myth (神话) of unicorns. But in the early nineteenth century, a French{#blank#}5{#/blank#} (science) named Baron Cuvier showed that unicorns were only a {#blank#}6{#/blank#} (product) of imagination.

    For hundreds of years before that, things were very different. Everybody{#blank#}7{#/blank#} (believe) that unicorns were real, but very few people saw them. Julius Caesar, who built the Roman Empire, ever said that the animal had the head of a deer, the {#blank#}8{#/blank#} (foot) of an elephant and a one-meter-long horn on its forehead. Marco Polo, who thought he saw a unicorn in India, agreed that it had elephants' feet and a horn, {#blank#}9{#/blank#} said it had a pig's head. He was almost certainly describing a rhinoceros(犀牛)! By the sixteenth century，when books about animals were {#blank#}10{#/blank#} (become)very popular, everyone agreed that the unicorn looked like a white horse with a horn.
